Works just fine. – Fly Delta Review

I don't see any of the problems everyone else has with this app. I didn't try to book a flight through it though. Let's me add my flight using name and confirmation, let's me check-in, and I can choose all of my seats. I can get mobile boarding passes. You can even see upgrade lists, you can't add yourself to one though. What more do you need?
